I don't know from your post what you are wanting to do with the drawings from fleetwood but if you are having trouble with the power disconnect switches you might get better information from RV Custom Products. They made your battery control center (aka BCC). They have published a troubleshooting guide that includes schematics and explanations way more detailed than what you will get from Fleetwood. You can find this documement linked or attached on this site by searching pretty easy.
